Adjustable Spot Cooler

Adjustable Spot Cooler from Nex Flow™

Adjustable Spot Cooler - Frigid-X™ is a low cost and maintenance free adjustable spot cooler system which utilizes a vortex tube to produce cold air at one end.

Adjustable Spot Cooler - Frigid-X™ temperature can be adjusted using a knob at the hot end to set the temperature precisely to your requirements. Temperatures range from approximately minus 30ºF to room temperature and can be easily set with a thermometer.

Adjustable Spot Cooler - Frigid-X™ comes with three brass generators for flow rate adjustment - 15 SCFM (425 SLPM), 25 SCFM (708 SLPM) and 30 SCFM ( 850 SLPM) providing refrigeration up to 2100 BTU/hr (615 Watts).

Adjustable Spot Cooler - How It Works

Adjustable Spot Cooler, Frigid-X, Adjustable, Spot, CoolerCompressed air enters at point (A) into the vortex tube component of the spot cooler. The vortex tube splits the compressed air into a hot (B) and cold (C) stream of air. The hot air from the vortex tube is vented to the atmosphere at point (D) after being muffled to reduce noise. Cold air enters into the muffler (E) and then distributed through the hose distribution kit (F) and onto the item being cooled. A strong magnet (G) holds the spot cooler in place. The temperature of the cold air is controlled by an adjustable knob.

Cold air is directed using the flexible tubing. A magnetic base is standard for portability and easy mounting of the adjustable spot cooler.

Units are available with either a single point hose kit for small surface area Adjustable Spot Cooler or a dual point hose kit when heat is generated over a larger surface area.

Adjustable spot cooler produces a wide range of airflow and temperature by adjusting the knob at the hot end and changing the various generators supplied.

The generators control the air consumption and are easily interchangeable.

Adjustable spot cooler has a 25 SCFM (708 SLPM) generator installed that will produce up to 1,800 Btu/hr. of cooling. If less is required, the 15 SCFM (425 SLPM) generator can deliver 1,100 Btu/hr.

If more cooling is needed Nex Flow™ can supply you with the 30 SCFM ( 850 SLPM) generator for up to 2,100 Btu/hr. of cooling.

Adjustable Spot Cooler - Operation

Adjustable spot cooler - Frigi-X™ creates cold air from a vortex tube.

Using an adjustable knob at the muffled "hot end", waste hot air exits the tube and controls the temperature drop at the "cold end".

Air exits the cold end and is directed using adjustable flexible tubing to the point of use. The unit is portable using a magnetic base.
